Description
Sukehisa Hamono Co., Ltd., located in Tokyo's Adachi district, built its reputation over decades by supplying commercial kitchens, traditional Tokyo butchers, and Western cuisine (Yo-shoku) restaurants in the capital's dining districts. The brand's philosophy was simple: utility, balance, and pure edge quality—no frills. The workshop was particularly known for its precise heat treatment of carbon steel—the yaki-ire and yaki-modoshi processes—which define the blade's character more than anything else. The workshop has since ceased production, and NOS Sukehisas are becoming increasingly rare on the used market.
A small Petty from the Gyuto line - the box describes it as 牛刀(ローズ柄 ペティ小型), “gyuto, rosewood handle, small petty.” The blade is stamped 登録商標助久特製 (Tokusei - special production). SK monosteel carbon steel, NOS condition in original box with manufacturer's leaflet.
